Fig. 2. Phylogenetic analysis of NDST enzymes.
The NDST proteins can be divided into three branches: NDST1 (yellow), NDST2 (green), NDST3 and NDST4 (blue). All proteins were retrieved from the National Center for Biotechnology Information (NCBI) database (35). The confidence level of each node was calculated with 100 boostrap replicates. Details of phylogenetic reconstruction described in Methods.
